Orbit and dynamics
Between its closest point (0.558 AU) and its farthest (1.268 AU), the heliocentric distance changes by 0.71 AU over every revolution.
One full revolution takes 0.87 yr (318 days), computed from the semi-major axis of 0.913 AU.
An eccentricity of 0.389 makes the orbit moderately elongated.
A steep inclination of 30° carries it well above and below the ecliptic plane.
By the vis-viva equation its orbital speed rises to 47 km/s at perihelion and falls to 20.7 km/s at aphelion.
Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.
Size and surface
The measured diameter is 0.15 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.256 points to a comparatively bright, reflective surface.
Observation record and orbit quality
Astrometry from 190 individual observations underpins this orbit; the fit leaves an RMS residual of 0.5933 arcseconds.
Condition code U = 0 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.
About these computed values
Orbital periods, perihelion and aphelion speeds, and diameter estimates on this page are computed by SpaceAtlas from the JPL SBDB orbital elements. They are derived quantities, not values copied from the source catalogue.
